目的：采用常压间歇性低氧(intermittent hypoxia,IH)大鼠的动物模型，观察间歇性常压低氧预处理的促血管生成作用。方法:成年雄性Wistar大鼠25只，体重210～215 g，随机分为2大组:对照组(C组，n=5)和间歇性低氧预处理组(IH组，n=20)。IH组动物进行间歇性低氧预处理(4 h/d，间歇缺氧1 d者为IH1组，7 d者为IH2组，14 d者为IH3组，28 d者为IH4组)，按计划完成实验后测定心肌血管内皮生长因子(VEGF) 蛋白表达及毛细血管密度。结果：间歇性低氧预处理大鼠心肌VEGF蛋白表达增加，心肌毛细血管密度增高。结论：间歇性低氧预处理能促进大鼠心肌内的血管生成，其机制可能与心肌VEGF表达增高有关。
